FLYING-.MACI-IINE.

Specification of Letters Patent.

Application filed February 3, 1912. Serial No. 675,102.

To all whom it may concern Be it known that we, JOHN MENZL and ELMER BURDG, citizens of'the United States,

residing at Dayton, in the countyof Montgomery and State of Ohio, have invented certain new and useful Improvements Flying-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to flying machines and more particularly to flying machines of the aeroplane type.

The object of the invention is to provide an aeroplane flying machine of such a character that it will possess a large degree of stability and may be easily controlled.

Further, it is an object of the invention to provide such a flying machine which will be simple in its construction and will have no complicated parts liable to become broken or disarranged when the machine is in the air.

In the accompanying drawings, vFigure 1 is a side elevation of a flying machine embodymg our lnventlon, showing the aeroplane in section; Fig. 2 is a rear elevation of the mechanism showing the plane in section; and Fig. 3 is a top, plan view of the flying machine.

The invention comprises, broadly, an aeroplane having its. breadth and length approximately equal and having a carriage,

upon which is mounted the engine and which carries the operator, suspended centrally from the plane. The'plane is dishshaped and is built about a central frame.

In the accompanying drawingswe have.

illustrated the aeroplane 1 as'substantially circular in shape. The plane preferably comprises a central frame, 2, of aluminum or other light material possessing the nec-' essary degree of strength. Extendingabout the frame is an annular band, 3, of rigid material, such as aluminum. This band may be substantially U-shape in cross section and has secured to both the upper and lower edges thereof series of wires 4 which are connected at their inner ends to the upperand lower portions, respectively, of the central frame 2. A covering 5 of fabric or other suitable material is stretched over the lower series of wires and forms the surface of the plane. This fabric preferably has its outer edge extending about and secured to the annular band or frame 3 and its inner edge secured to the central frame 2. Mo-

propellers mounted at the front and rear, respectively, of the plane and preferably carried by shafts 8 to which rotatory movement is imparted by means of Worm and worm wheel gearing 9, the latter being con- PatentedNov. 25, leis.

- tion is imparted to the plane by means of nected by means ofthe flexible shaft 10 with an engine 11. The engine 11 is preferably mounted upon a carriage or supporting platform 12 suspended centrally from the plane 1 and which is also designed to carry the operator. The rise and fall of the machine may be controlled by tilting the plane as a wholerelatively to the carriage 12, the latter being pivotally connected to the plane on a transverse axis, as indicated at 13. This movement may be, imparted from the carriage 12 by means of cables 14 connected at their opposite ends to the front and rear ends, respectively, of the central frame 2 and passing about drums 15 carried by a shaft 16 mounted on the carriage 12 and provided with an operating handle 17. We have also provided a horizontal rudder 18 mounted near therear of the plane and controlled by means of cables 19 extending to apoint near the carriage or platform 12. A rudder 20 is also mounted above the plane and provided with a controlling shaft 21 extending downward to a position near the carriage 12 and provided with a steering wheel 22.

It will be understood that the rudders for controlling, the direction of movement of the plane are shown merely for the purpose of illustration and as these may be of any well known character they are not shown or. described in detail. of the invention consists in providing a plane having its length approximately equal to its width and the carriage supported centrally thereof, the plane being preferably dish-shaped. It will, therefore, be further understood that we do not wish to be limited to the details of construction shown and. described, for obvious modifications will occur to a person skilled in the art.

7 Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is V 1. In a flying machine, the combination with a circular plane including a centrally disposed frame, of propellers respectively mounted at the front and rear ends of said plane, and a carriage disposed below and pivotally connected directly to the frame The essential feature i on a transverse axis whereby said plane and carriage may have longitudinal swinging movements relative to each other.

1 2. In a flying machine, the combination vwith a circular plane including a centrally disposed frame, of a propeller mounted at one end of said plane, a carriage disposed below and pivotally connected directly to swinging movements relative to each other,

'a horizontal rudder pivotally mounted onsaid plane, and a connection between the carriage and the rudder for automatically shifting the latter upon movement of the 15 former.

In testimony whereof, we aflix our signatures in presence of two witnesses.
